To save lumber you could make them only 6 ft, you could make them 5 ft, most people won't be trying to scale them anyway, them somebody could hide and pop up for an anyplace scare if all the walls were 5 ft.

Most haunts I've seen and ours we build are 8ft. At the Darkness I think I've seen them use 12 ft walls and I have an idea how they do those. But they also build them to the ceiling as well. There interlocking wall system is also very impressive. No bracing involved! Larry should make a video on some of these building techniques alone. They could make a small mint from it. Some very impressive stuff.

Mr. Haunt -- Most walls are 8' high simply because most wall panels are made from standard sheets of plywood (4' X 8'). You can, of course, make walls any height that you choose, but if vary from the standard you are adding additional labor and expense.

I have always wondered why the thin (crappy) osb wafer board is used, doubled up on two sides of a 2 by 4?
If you wanted strength, thinner walls (easier to store and configure), why not use the albeit, more expensive per/sheet, but only use one sheet, of 3/4 inch plywood instead, it will take paint 50 times better, not be abrasive with flakes and be much quicker to build,easier to lay flat and store since no 2 by 4s would be used.

We are a temporary haunt, everything gets tore down at the end of the year and put back together again the next year... I really don't feel like lugging around 3/4" plywood for 2 months. The skin on our walls is only 1/8" thick, our house gets the snot beat out of it and we've never had a problem with durability. If you just put some simple frame work inside the walls it won't break when impacted.

I'll second that motion! That's a great idea! I'd still love to see footage of the creation of the sets using the blown insulation foam as well!

With a full time location you can go 16 - 20 feet tall with your scenes. Just keep in mind that if you ever lose your location moving these monsters is hellish if you don't build them with mobility in mind. Learning the hard way sucks..... :evil:

I have never seen a haunt in a non-full time location use more than an 8 foot wall system. I would like to see someone who has accomplished mobile, easy to use, sets over 8 foot.

.....and.... I wouldn't mind knowing how Larry built the Darkness stuff...
